3 PS302P - Fieldbus Power Supply AVOIDING ELECTRICAL DISCHARGES ATTENTION Electrostatic discharges may damage semiconductor electronic components in printed circuit boards. They usually occur when touching components or connector pins from modules and racks, without wearing the appropriate equipment to prevent discharges. It is recommended to take the following precautions: Before handling modules and racks, remove the electrostatic charge from your body by wearing a proper wristband or touching grounded devices; Avoid touching electronic components or connector pins from racks and modules. 3

4 PS302P - User s Manual PS302P - POWER SUPPLY FOR FIELDBUS Description These modules were specially designed to supply the fieldbus networks. The only difference between them is the input voltage: PS302P (90 ~264 Vac) PS302P DC (20 ~30 Vdc) The PS302P power supply unit is a non-intrinsically safe equipment with a universal AC input (90 to 264 Vac, 47 to 63 Hz or 127 to 135 Vdc), and a 24 Vdc output, isolated, with short circuit and overcurrent protection, ripple and fault indication, appropriated to supply fieldbus elements. The PS302P DC power supply unit is a non-intrinsically safe equipment with a DC input (20 to 30 Vdc) and a 24 Vdc output isolated, with short circuit and overcurrent protection, ripple and fault indication, appropriated to power fieldbus elements. The interconnection of fieldbus elements to the PS302P/PS302P DC is indicated in the figure below. There is no overshoot when it is switched on or off. The PS302P/PS302P DC can power on up to 4 fully loaded fieldbus networks. NOTE The length of the cables that interconnect the PS302P/PS302P DC modules to DF53/DF98 must not exceed 3 meters. If any abnormal condition occurs in the output such as overloading or short circuit, the PS302P/PS302P DC internal switching is automatically switched off, thus protecting its circuit. Upon the outputs return to normal conditions of operation, the circuit is automatically switched on. The PS302P/PS302P DC allows redundancy without requiring any component coupled to its output.

7 PS302P - User s Manual Installing Modules in the Rack Follow the steps below to install a module in the rack. Attach the top of the module (with a 45 o inclination) to the module support located on the upper part of the rack. Mounting detail. Push the module fixing it to the module connector. Next, fix the module to the rack using a screwdriver, and fasten the fixation screw at the bottom of the module. 7
